Title: Print system for facsimile picture
Inventor: TAKAYAMA SHIYOUICHIROU
IPC: B41J2/485
Filed: 1979-11-30
Abstract: PURPOSE:To reduce the price of a printing head and to improve picture quality by checking the mean density of a print sample area and by performing printing operation with a difference in density according to the check result. CONSTITUTION:An original signal, read in time series, is inputted to terminal 31, sampled by clock 32 for many samples and then inputted to counter 33. Counter 33 counts up only the black ''1'' signal of the sampled original signal and, after counting up to 16, the total of the black ''1'' signal is regarded as the mean density of a print dot space. The output of counter 33 is written in RAM35 by way of two-way driver 34. The address of RAM35 is assigned by counter 39, which is put into operation by the clock obtained by frequency-dividing clock of 1/16 of clock 32. Gradation information written in RAM35 is read out as required and compared with a value assigned from terminal 40 by comparator 37 to pick up dots to be printed at that time. Thus, even if gradation print operation is performed with a rough-density head, the deterioration of the picture quality can be prevented.

CONSTITUTION:Hollow metal tubes 2, small in its thickness and diameter, are at first manufactured by way of extrusion or other method, and a hollow metal tube  group is formed by inserting the tubes 2 into a container 1 in a straight or spiral  manner and in a side-by-side relationship with each other, and welding (at 4) them to the inner wall surface of the container 1. Then, the tubes 2 are cut at their wall portions located at a heat absorbing section A and a heat emitting section C and facing  the center of the container 1, so that they are opened toward the center of the container 1. Here, the sectional form of the openings is determined to suit the use of the heat pipe. In such an arrangement, condensed liquid at the section C is introduced into  the tubes 2 from the openings and carried through an intermediate section B. Then, it  is evaporated at the section A and discharged into the container 1 from the openings.  Thus, it is enabled to improve the performance of the heat pipe.

Title: Silencing union joint with acceptor
Inventor: HANAKAWA YORI
IPC: F16L55/02
Filed: 1998-06-03
Abstract: PROBLEM TO BE SOLVED: To reduce the noise when the water flows in a piping by forming an inner layer including a water flowing surface of a joint body with an elastic resin having a specific hardness, and making the flowing water surface flush with the flowing water surface of a pipe to be joined. SOLUTION: The total layers of the acceptors 12, 12 and an outer layer of a joint body 11 are made of a synthetic resin 1B, and an inner layer including the water surface of the joint body 11 is made of an elastic resin 1A having the hardness at most 80. A thickness t1 of a part made of the elastic resin 1A is equalized to a thickness of a synthetic resin pipe 2, and the flowing water surface in the joint body 11 is flush with the flowing water surface in the inserted synthetic resin pipe 2. The piping is performed by connecting the synthetic resin pipes 2, 2 to the acceptors 12, 12 at both ends of a union joint 1. When the fluid flows down in the piping, the inner layer including the water surface of the joint body 11 made of the elastic resin 1B having the hardness at most 80, absorbs the impact generated in the flowing of the fluid, whereby the noise can be reduced.

Title: Reflection diffraction type chromatic aberration compensating element and chromatic aberration compensating device
Inventor: MARUYAMA KOICHI
IPC: G02B5/18
Filed: 1993-06-25
Abstract: PURPOSE:To excellently compensate a chromatic aberration by equipping a regular projection shape for a plane, orthogonal to an optical axis with a reflecting surface composed of a center reflecting surface which is rotationally symmetric about the optical axis and many zone reflecting surfaces concentric with it. CONSTITUTION:The reflection diffraction type chromatic aberration compensating element 11 consists of the circular center reflecting surface 11ac which has its center on the optical axis O and the coaxial circular zone reflecting surfaces 11bc-11dc which are positioned outside the reflecting surface and having circular contours. The circular center reflecting surface 11dc and circular zone reflecting surfaces 11bc-11dc consist of mutually parallel plane groups and are different in position by a step distance (t) in the direction of the optical axis O to form a macroscopically convex shape on the whole. Therefore, when the reflecting surfaces are in a staircase shape of the step distance t(h)=lambda/2n (h: distance from optical axis O) or its integral multiple (m), light with reference wavelength lambda is reflected in adjacent reflection areas and the reflected light deviates exactly by mlambda and travels without changing the shape of the wave front.

Title: Substrate for electronic component
Inventor: KANBARA SHIGERU
IPC: H01G13/00
Filed: 1998-06-04
Abstract: PROBLEM TO BE SOLVED: To provide a substrate for electronic components which can be divided into pieces without causing defective shapes by extending breaking grooves at both the ends of the substrate in one direction to the edges of the substrate and forming the breaking grooves in one direction deeper than those in the other direction except at the breaking grooves at the both ends in the one direction. SOLUTION: Breaking grooves 2, 2', 3, and 3' are formed in a grid-like state on the surface of a substrate 1 except the frame-like peripheral edge sections 1a and 1b of the substrate 1. All of the grooves 2, 2', 3, and 3' are formed by press working, and the depths of the grooves 2', 3, and 3' are adjusted to about 5-50% of the thickness of the substrate 1. The depths of the breaking grooves 2 are adjusted so that the depth of the grooves 2 reach around the rear surface of the substrate 1. Here, since peripheral edge sections 1a and 1b are retained the substrate 1 is prevented from being broken into pieces at the grooves 2. Therefore, strip-like substrates can be obtained without generating defective shape, because the substrate 1 can be divided into substrates without causing defective shapes in the broken end faces of the substrates in one direction.

Filed: 1988-06-23
Abstract: PURPOSE:To achieve a smaller size and a higher sensitivity by employing a flat plate type conduction medium having a plane or a gentle curved surface as photoconductive medium. CONSTITUTION:A photoconductive medium 10 employs a flat plate type conduction medium having a plane or a gently curved surface and a device serving as incident light section 12 and light receiving section 13, for example, prism is provided adjoining a horizontal surface of a flat plate. A light reflecting layer 13 is formed on a part or the whole part of a side except for the incident light section 12 and the light receiving section 13. More than one materials that changes in a complex index of refraction when contacting a gas and is different in sensitivity are prepared and a coating is applied on one of horizontal surfaces of the flat plate divided into two layers to form gas detection layers 11 (11a and 11b) (illustrated in Fig. d). When refractive indexes of the light transmission medium 10 and the detection layers 11a and 11b are represented by n1-n3 (e.g. n1<n2<n3), light is propagated through a plane transmitting and reflecting through the layer 11 while the quantity of transmission light varies with a change in the complex index of refraction of the detection layer 11. Thus, incident light is reflected many times within a broad surface of the plane and reaches the light receiving section lengthening a light propagation optical path.
